I'll keep this short.

1st run with Pro-M, PSP chip and newly installed full Bassani 13.49@101.94

2nd run with all of the above plus the single blade TB 13.47@102.50

I guess it helped on the track, here comes the strange part. Went to the dyno with Jerrod "99svt" this morning. Here is the results.

347rwhp and 418rqt

What, you have to be kidding me, my truck is running stronger than ever and I just dynoed at Houston Perf. 3 weeks ago at 367rwhp and 436rwt.(before full Bassani ans TB) Jerrod also dynoed today at 349rwhp and 430rwt. We have the exact same mods. so our numbers should have been about the same and they were except the torque. Most people on this board are up the 370s or 380s with the same mods but they are running about the same times at the tracks as Jerrod and I. If I were to measure the horsepower at the shift spikes I would be at 377rwhp, could some be doing this or is one of the dynoes (Houston Performance and Colvin Auto.)off or something. The correction factor today was 1.07. Keep in mind I dynoed at 320.5rwhp and 408rwt stock at the same place. Could all of my mods only be worth less than 30rwhp and 10rwt? Any comments welcome. Sorry, I know I said I would keep this short.

 

Yeah, don't know what is up with this. I think that some people are posting there spikes, because that is the same as the spikes that I have. This is the first time I have been on a dyno, but these figures are low compared to others with the same mod. Going to try Houston Performance in Houston next week to see the difference.

What brand of dyno was it?

 

I think that you are corect (99SVT) when you state that some people are posting their spikes. Those spikes are not at the shift because you should be pulling from third gear. The spike that you see is in all Lightnings I have tested my Lightning with both CUX1 and CUX2 and the spike is there. I have also tested all of the major tuner chips and the spike is there with the exception of one the Inject-Tech chip. On the Dyno-Jet dyno the spike gets plotted as max. HP and Torque. What you may be seeing as horsepower and torque differences between the two dynos (assuming they are the same) is calibration levels. Do you know the software calibration level for the dynos are they both the same. Also I hate to say this but some operators set their dynos up to give sweet numbers. One last item the throttle body will help to free up the intake side but there could still be a restriction on the exhaust side. Watch for "High Risk" to post there will be no restrictions in his system ---- intake or exhaust.

Caka,
that sounds about right.I ran a 13.47 @ 102.1mph at the track on friday night.

Mods:
PSP Chip
Airaid
3.73 Gears

 

Caka,
How's your intercooler leverl? The reason I ask is because my previous best dyno run was a 378rwhp and 442rwtq and my mods included full bassani, prom-80, Houston Performance chip. I went back a few months later and did some tuning on the chip with Michael Senroy and noticed that my rwhp was down to something like 350. We also noticed that the intercooler was a little low. So we filled it up and tried several more times. No go. Well I went home happy with the tuning changes, but un-happy with my dyno numbers. A few days later I popped the hood to check my intercooler and boom it was half full. I filled it back up and again a few days later half full. Anyway to make a long story short my truck is now at TMV getting a new intercooler, plugs, o2's, gaskets, etc. As soon as I get it back I will be going straight to the dyno to see if my missing horsepower has returned (which I am sure it has). Food for thought.

Oh and one last thing that was not my spike numbers, which as you stated most people are using. One thing Michael noticed was that depending on how he "rolled-on" the throttle would directly affect wether or not we had a spike on the dyno graph. And trust me with 20+ dyno runs we had a ton of time to try different things, including nitrous across the intercooler

BTW...it does not work very well in case you are curious.

Caka,

Do you know how much rwhp you gained from the Pro-M? Did you have the PSP chip recalibrated for it? This is not Sal's MAF is it?

I dynoed a couple days ago with 360 rwhp (not the shift spike) without the Pro-M but with a Swanson chip and Danny said I could expect another 20rwhp with the Pro-M, but would have to have the chip recalibrated for it.

Also the shift spike on mine went up over 440 hp and 582 torque I wonder if this could be in part from the shift kit?

Mike

 

Hey Guys!
It is not a shift spike. Your dyno guy should not even be doing the pull through a gear change. The spike that you see is due to a FU in the EEC. Well I guess it is a shift spike sorta like its on, its off, its on again.
PS. Try explaining this one to your dealer. Oh. Mr. service writeup man when I was dyno testing my Lightning I notices a screw up in the EEC that gives me a spike in HP and Torque can you fix it for me.
Here are two questions for you. If you see this spike on the dyno. What do you think it is doing to your vehicle on the road / track. Why can it be removed with a certain chip?

BRIMSTONE, on back to back dynoes at Hou. Perf. with PSP chip& airaid 355rwhp then with Pro-M & PSP chip 367rwhp. No adjustment to the chip is reccommended by Superchip or PSP

 

Caka if you would call me @ work I'd like to ask you a few question about your set-up/truck, mabey I can help with the lack of HP!

Thanx!

Your Bassani installer!

 

FWIW, yes my coolant level was only about 1/4 full. Dont know if it has anything to do with the HP but but I guess its possible. I filled it yesterday and it took about 3/4 gallon of water. Looks like I will be getting that fixed next.

Hey Jerrod, when you go to H.P. next week be sure and get all of the print out and show them the print outs from Colvin, I'm curious to see what they have to say.

 

including nitrous across the intercooler.

BTW...it does not work very well in case you are curious.

Only knocked 1 second off my 1/4 mile times.

spraying nitrous directly in front of your external heat exchanger knocked a full second off your ET???

Hmm...on the dyno it was only worth 10 or 12 rwhp.

well....I guess I should have included your results may vary.

And what "certain" chip might that be? Ha Ha Don't say it. It might Inject some flamin' 'round here. J/K all

 

Hey guys,

I can't really answer Caka's question, except to suggest that maybe one dyno used STD correction vs. SAE correction factor. I still have yet to have anyone actually explain the differences in these correction factors (I guess they are "correcting" to different standards?). Anyway, is this a possibility?

As far as the spike goes...I know exactly what BaBolt is referring to. I've seen it on just about every pull I've made. It happens ~4800rpm it seems.

However, what was strange is that when I tested recently with my PSP chip vs. Superchip deal, I didn't see the spike on the PSP chip runs. Weird.
